DANOPLUSDecibel Meter Wall Hanging Sound Level Meter 11 inch Large LED Display Noise Temperature Humidity Meter with Alarm Icons Indicator Wide Applications for Classroom, Studio, Home, Factory

The first one they shipped me was glitchy. It kept showing weird measurements, for example flipping to 130DB in a completely quiet environment. It was really distracting and completely unusable. I tried recalibrating it several times per the instructions. No luck.But I liked the large numbers so much (really easy to read from across the room) that I decided to give it another chance and exchanged it. The second one worked perfectly right out of the box with no issues.I use it in my office when I'm on Zoom calls for work. I tend to speak loudly at the computer and this helps me moderate my volume so the rest of the household doesn't get frustrated. The display includes a color coding of green/red/yellow emojis, so it's easy to tell when your volume exceeds the acceptable threshold.Highly recommended!

My students had no idea just how loud they can get. Now they can see, monitor, and regulate their voices. Ideal class noise level should be between 55 to 60 dB. When they see they often approach 70 to 90 bB, I tell them this is where you start having long-term hearing loss.

Looks brilliant and fun to watch if that's your thing but some of the measurements are a bit mad. You can calibrate it somewhere quiet but it still said my bedroom was 98odd dBA at 4am today so either I was missing something dramatic going on under my nose or it's not the most accurate device in the world. The fast response mode is a bit less extreme but is a bit too busy to have on and not distract people.I think it will grow on me more

I bought this to put on the wall behind my sons gaming computer. He gets playing games with a headset on and gradually gets louder to the point of yelling while playing online. I set it up so that all he sees are the faces. He knows that green or yellow are ok but if they go orange or red he is too loud. We used to get into arguments because he would get upset when he was told he was being too loud. Since i put this in place there hasn't been a single argument and we aren't being disturbed.

Needed this device because a neighbor was complaining about hearing noise bleeding through a common wall from my home theater. This device allows me to monitor the decibel level in real time and adds objectivity to any perceived issues. Easy to set up and use. LED display is easy to read from a distance. No problems with the meter so far. This particular brand was also $10 cheaper than a competitor on Amazon for the same product.
